Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones

open access: yesAdvanced Functional Materials, EarlyView.
Ru‐substituted hexagonal perovskite SrMnO3, featuring face‐shared oxygen species, is designed as an effective heterogeneous catalyst for the aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (>99%) under mild reaction conditions (≥30 °C). Ru substitution promotes oxygen vacancy formation of face‐shared oxygen species

Turning on Selective H2S Gas Sensing Activity in Ternary Nickel Tungstate Strongly Correlated Electron System Through Sub‐Gap Band Manipulation

open access: yesAdvanced Functional Materials, EarlyView.
A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.
